[0028] In most of the existing electric energy conversion apparatus, a cover plate is providedon one side of a case to form a ventilation passage, and an air outlet cover is arranged at anupper end of the cover plate, and a natural airflow takes away the heat of the case through theventilation passage, and then the heated air is guided to the outside of the case from air outletsaround the air outlet cover, so as to heat dissipate the electric energy conversion apparatus. Inthe existing electric energy conversion apparatus, the air outlet cover is covered on the top ofthe electric energy conversion apparatus and the cover plate in most cases, so that an overallarea of the air outlet cover can be increased according to the demand, thus increasing the airoutlet area. However, the heated air flowing into the air outlet cover through the ventilationpassage can easily leads the heat to the electric energy conversion apparatus at the top of theelectric energy conversion apparatus, which affects the heat dissipation effect of the topdevice of the electric energy conversion apparatus, resulting in poor overall heat dissipationeffect of the electric energy conversion apparatus. In view of the above problems, a heatdissipation assembly 100 is provided according to the present application.

[0029] Referring to FIG. 1 to FIG. 5, in the embodiment of the present application, the heatdissipation assembly 100 includes a side cover 10 and an air outlet cover 30, the side cover 10is connected to the electric energy conversion apparatus 300. A heat dissipation passage 111is formed by enclosure of the side cover 10 and a side surface at one side of the electricenergy conversion apparatus 300, the side cover 10 is provided with an air inlet 131 incommunication with the heat dissipation passage 111; the air outlet cover 30 is arranged at thetop of the electric energy conversion apparatus 300 and partially connected with the sidecover 10, and an air outlet space 31 is formed by enclosure of the air outlet cover 30, and theair outlet space 31 is in communication with the heat dissipation passage 111, the air outletcover 30 is provided with an air outlet 33, in communication with the air outlet space, at anouter peripheral side away from the electric energy conversion apparatus 300; a partitionmember 37 is arranged in the air outlet cover 30, the partition member 37 is arranged in theair outlet space 31 and connected to the top of the electric energy conversion apparatus 300. Aconvection passage 3711 is formed by enclosure of the partition member 37 and the uppersurface of the electric energy conversion apparatus 300, and a convection port 35 incommunication with the convection passage 3711 is arranged on the outer peripheral side ofthe air outlet cover 30.

[0030] According to the technical solution of the present application, the heat dissipationpassage 111 is formed by enclosure of the side cover 10 and one side surface of the electricenergy conversion apparatus 300, and the top of the electric energy conversion apparatus 300is provided with an air outlet cover 30, so that the air outlet space 31 enclosed by the air outletcover 30 is in communication with the heat dissipation passage 111, and then a natural air canflow into the heat dissipation passage 111 from the air inlet 131 on the side cover 10 to takeaway the heat on the electric energy conversion apparatus 300, and then heated air can flowinto the air outlet space 31 and then is discharged from the air outlet 33 of the air outlet cover30 on the outer peripheral side away from the electric energy conversion apparatus 300, thusrealizing the heat dissipation of the electric energy conversion apparatus. By providing thepartition member 37 in the air outlet cover 30, the air outlet space 31 can be separated fromthe top of the electric energy conversion apparatus 300 by the partition member 37, so as toavoid direct contact between heated air in the air outlet space 31 and the top of the electricenergy conversion apparatus 300, and reduce the heat of the heated air leading to the top ofthe electric energy conversion apparatus 300. In addition, a convection passage 3711 isformed by enclosure of the partition member 37 and the upper surface of the electric energyconversion apparatus 300, so that the natural air can enter the convection passage 3711 fromthe convection port 35 of the air outlet cover 30 and takes away the heat of the partitionmember 37 transferred by the heated air and the heat at the top of the electric energyconversion apparatus 300. Meanwhile, under the action of the partition member 37, the airoutlet space 31 of the air outlet cover 30 can be divided into a heated air outlet area forleading out the heated air of the heat dissipation passage 111 and a natural air convection areafor heat dissipation to the top of the electric energy conversion apparatus 300. Therefore, theheat dissipation passage 111 has a function of simultaneously heat dissipation to one side ofthe electric energy conversion apparatus 300 and to the top of the electric energy conversionapparatus 300, thereby effectively improving the overall heat dissipation effect of the electricenergy conversion apparatus 300 and improving the practicability and reliability of theelectric energy conversion apparatus 300. In addition, the air outlet 33 is arranged on the outerperipheral side of the air outlet cover 30 away from the electric energy conversion apparatus300, so that the heated air can be dissipated to the outside of the electric energy conversionapparatus 300 in the direction away from the electric energy conversion apparatus 300,thereby further reducing the heated air applying on the top of the electric energy conversionapparatus 300 and improving the overall heat dissipation effect of the electric energyconversion apparatus 300.

[0031] In this embodiment, the top plate of the air outlet cover 30 away from the electricenergy conversion apparatus 300 is detachable, and according to the actual use requirements,users can remove the top plate of the air outlet cover 30 and increase the height and air outletarea of the air outlet cover 30 in order to provide the heat dissipation assembly 100 with abetter heat dissipation effect and further improve the practicability of the heat dissipationassembly 100.

In addition, under the action of the partitionmember 37, the air outlets 33, on both sides of the part where the air outlet cover 30 coversthe partition member 37, can be far away from the heat dissipation passage 111. In that case,during the foreign matter, which enters the air outlet space 31 from the air outlets 33 on bothsides of the air outlet cover 30, is being moved towards the heat dissipation passage 111, dueto the long distance, some foreign matters are accumulated on the surface of the partitionmember 37 away from the electric energy conversion apparatus 300 under the action ofgravity, and thus the foreign matters entering the heat dissipation passage 111 are furtherreduced, which further improves the heat dissipation effect of the heat dissipation assembly100. For daily use, it is only necessary to remove the air outlet cover 30 in order to clean theforeign matters entering the heat dissipation assembly 100, which facilitates of themaintenance of the heat dissipation assembly 100 and further improves the practicability ofthe heat dissipation assembly 100.
